jpa整合spring

首先引入该引入的包

最重要的就是beans.xml的配置

附上

　　　　

<?xml version="1.0" encoding="UTF-8"?>

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

 <aop:aspectj-autoproxy/>
 <context:component-scan base-package="cn.itcast"/> 
    <!--  使用数据源和指定persistence.xml位置的方式创建entityManagerFactory,如果使用的不是hibernate JPA实现,
    需要在tomcat作一些特殊配置.具体参考手册
    注意:使用该方式需要把persistence.xml中的hibernate.connection.driver_class,hibernate.connection.username,hibernate.connection.password,hibernate.connection.url配置删除

还有persistence.xml中的配置

<?xml version="1.0"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" version="1.0">
  <persistence-unit name="itcast" transaction-type="RESOURCE_LOCAL">
   <provider>org.hibernate.ejb.HibernatePersistence</provider>
 <properties>
         <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect"/>
         <property name="hibernate.max_fetch_depth" value="3"/>
         <property name="hibernate.hbm2ddl.auto" value="update"/>
      <property name="hibernate.jdbc.fetch_size" value="18"/>
      <property name="hibernate.jdbc.batch_size" value="10"/>
      <property name="hibernate.show_sql" value="false"/>
      <property name="hibernate.format_sql" value="false"/>
      </properties>
  </persistence-unit>
</persistence>
